METHOD OF EXTRACTING CONE-S FROM MALE AND FEMALE MOLDS.

Application filed November 21, 1925. Serial No. 70,655.

T 0 all whom it may concern:

Be it known that I, ALBERT E. DIETERICH, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented certain new and useful Improvements in Methods of Extracting Cones from Male and Female Molds, of which the following is a specification.

My invention relates to the art of ice cream cone baking in split female molds having cores or male elements and the invention particularly has for its object to provide means for extracting the cones from the mold units without the use of the core as an extracting finger.

In the present general practice of extracting cones from their molds as actually employed in the art, the cones are released by first effecting a slight lift of the core and subsequently separating the female mold sections while permitting the core to remain projected within the cone, thereby to act as a stripping finger.

My present invention provides a practical and effective means for accomplishing the extracting result without, however, employing the core or any core equivalent as an extracting finger by utilizing the cone structure itself to effect a detachment from the female walls.

In the drawing I have diagrammatically I illustrated my invention and by reference to which it will be seen that Figure 1 is a diagrammatic vertical cross section of a mold and core unit in the baking position. V

Figure 2 is a unit of Figure 1 after the core has been removed, showing the cone remaining in the female cavity.

Figure 3 shows the second step of the extraction (the first step of the extraction from the female mold cavity).

Figure 4 is another View similar to Figures 1 and 3 showing the third step of extraction (the second step of the extraction from the female cavity).

Figure 5 indicates the final step of the extraction.

Figure 6 is an enlarged detail view in section of the suction plate.

In the drawing 11 designates the female mold sections, 2 the core and 3 the core bar, all of which may be of the usual construction.

t designates a suction plate which may be faced with a suitable pad 5 (or left unfaced if desired) and which is adapted to be con-.

nected with a suitable suction producing or emcuatingapparatus (not shown) to the neck duct 6. r

In conducting my method of extracting after the cone has been-baked in the usual way the core 2 is wholly removed while the female sections 11 remain closed and locked. I thereafter place over the female mold cavities from which the'core has been removed a suction plate 4-5 to contact the mouth of the cone and apply suction tending to produce a partial vacuum within the cone itself, thus holding the cone by suction to the suction plate with the mouth of the cone pressed in engagement with the suction plate by atmospheric pressure, thereby holding' the cone against lateral movement when the mold sections are separated as shown in Fgure 4. After the mold sections have separated sufficiently the suction is broken and the cone permitted to drop by gravity, or air under pressure may then be passed through the duct 6 downwardly to blow the cone down through the female mold.

The degree of suction used will depend of course upon the tenacity of the sticking encountered in practice. With cones that stick considerably a greater suction will be required than with cones which have but light adherence to the female cavities.

From the foregoing description, taken in connection with the accompanying drawing, it is thought that the operation and advantages of my invention will be clear to thoseskilled in the art to which it relates.

What I claim is: v

'1. The method of extracting cones from male and split female molds which consists in first removing the core from the baked cone while holding the cone against core following movement, then closing the mouth of the cone and reducing the air pressure within the closed cone while separating the sections of the female mold from the cone 'and finally increasing the pressure within the cone to cause the cone to drop.

2. The method of extracting cones from male and female molds of the split female mold type, which comprises the following steps: removing the core from the cone held within the female mold, placing a restraining body over the mouth of the cone, causing a reduction of air pressure beneath the body to suck the cone toward the body while holding the body against lateral movement and separating the female mold, and there after restoring the initial pressure beneath the body to permit the cone to drop.

3. The method of extracting cones from male and female molds of the split female mold type, which comprises the following steps: removing the core from the cone held Within the female mold, placing a restraining body over the mouth of the cone, causing a reduction of air pressure beneath the body to suck the cone toward the body While holding the body against lateral moven'lent and separating the female mold, and thereafter restoring the initial pressure beneath the body to free the cone from restraint, and subsequently blowing the cone from beneath the body.

4. The method of extracting cones from male and-split female molds which consists in first removing the core from the baked cone While holding the cone against core following movement, then reducing the air pressure Within the cone while restraining the cone against rising in the mold, and separating the sections of the female mold from the cone, and finally increasing the pressure Within the cone to cause the cone to drop.

5. In the method of extracting cones from male and split female molds, the steps which consists in first removing the core from the baked cone while holding the baked cone against core following movement, then applying suction focalized around the axis of the cone at the mouth of the cone to tend to hold the cone in a central position, while separating the female mold sections whereby the cone is caused to release itself from the female mold Walls to which it has a tendency to adhere, and then increasing the pressure Within the cone to cause the cone to drop.
